The fire bolt struck Gemayel’s left hand after it bounced off a ring of keys on his desk, he told InsideEdition.com Thursday.

"It's good to be alive," he said. "It was a pretty crazy experience."

Gemayel, 36, told InsideEdition.com that he had just returned from a doctor's appointment to follow up after Monday's mega-volt experience.

His body is still reacting to being zapped, he said. Goosebumps appear for no reason, and his internal temperature "keeps going from hot to cold," he said.

He has been told to drink massive amounts of liquid to flush his kidneys because a possible side effect of being struck by lightning is kidney failure, he said.

Gemayel said he just doesn't feel right.

"It's like being run over by a truck, to tell you the truth," he said. "I just don't feel like myself."

He said he didn't even realize he'd been hit until hours later, when his hand began to blister, he said.

"I didn't know at first," he recalled. "I was running around frantically" to make sure nothing was on fire and to check on some high-end automobiles in his shop, including a Lamborghini. He ended up driving himself to the emergency room after he began to feel "really foggy" and achy, he said.
